Cosmetic composition containing at least one surface-active agent of the alkyl polyglycoside and/or polyglycerolated type and at least one polyetherurethane

ABSTRACT

The invention relates to a cosmetic composition containing in a cosmetically acceptable medium at least one nonionic surface-active agent of the family of alkyl polyglycosides and/or a polyglycerolated nonionic surface-active agent and at least one polyetherurethane, as well as a process for cosmetic treatment consisting in applying to the skin or the hair a cosmetically effective amount of this composition.

This application is a continuation of application Ser. No. 08/014,989, filed Feb. 8, 1993, abandoned.

The invention relates to cosmetic compositions containing at least one nonionic surface-active agent of the alkyl polyglycoside and/or polyglycerolated type and at least one polyetherurethane.

U.S. Pat. No. 4,155,892 essentially describes the use of some polyetherurethanes for thickening latex-based paint compositions.

Polyetherurethanes are moreover known as thickeners for compositions containing surface-active agents. Europena Application EP 260 430 describes polyetherurethanes capable of being used in cosmetics for thickening oxyethylenated fatty alcohols containing 8.5 to 15 moles of ethylene oxide, and oxyethylenated sorbitan monoester containing 20 moles of ethylene oxide.

Surface-active agents of the family of alkyl polyglycosides or polyglycerolated agents have already been recommended in washing compositions for the hair or the skin. They are mild detergents which are well tolerated and are biodegradable.

Hair which is attacked by environmental agents such as light or chemical treatments, and washed with conventional washing bases, is difficult to disentangle and this disadvantage is increased further in the case of fine hair. The compositions, containing polyetherurethanes and nonionic surface-active agents, described in European Application EP 260 430 do not confer disentangling properties.

The applicant has just discovered, surprisingly, that the combination, in washing and/or treating compositions for keratinous materials, of polyetherurethanes with special nonionic surface-active agents of the alkyl polyglycoside and/or polyglycerolated type conferred on these compositions substantially improved disentangling properties. Moreover, the combination conforming to the invention makes it possible to obtain a very mild foam compared with the generally harsh foam resulting from the use of nonionic agents.

Furthermore, the applicant observed that compositions containing such a combination had good cosmetic properties such as mildness and a pleasant feel.

The subject of the present invention is therefore cosmetic compositions containing at least one nonionic surface-active agent of the alkyl polyglycoside and/or polyglycerolated type and at least one polyetherurethane.

Another subject of the invention consists in the use of these compositions for treating and/or washing keratinous materials such as the hair or the skin, hair being particularly preferred.

Another subject of the invention consists in a process for the cosmetic treatment of the hair or the skin by means of the compositions conforming to the invention; the process for washing and treating hair being particularly preferred.

Other subjects of the invention will emerge on reading the following description and examples.

The cosmetic compositions according to the invention contain, in a cosmetically acceptable medium, at least one nonionic surface-active agent of the alkyl polyglycoside and/or polyglycerolated type and at least one polyetherurethane.

Among the polyetherurethanes which may be used according to the invention, there may be mentioned those of the following formula (I): ##STR1## in which, [(C₃ H₆ O)(C₂ H₄ O)].sub.(b.sbsb.1.sub., a.sbsb.i.sub.), with (b_(i), a_(i)) denoting (b, a) or (b', a'), means that is a random polymer of propylene oxide and ethylene oxide containing a mole of ethylene oxide and a mole of propylene oxide distributed in a random manner in the polymeric chain,

A denotes a divalent radical derived from an aliphatic, cycloalophatic or aromatic diisocyanate, preferably a divalent radical derived from a polyethylene diisocyanate, tolylene diisocyanate or methanediphenylene diisocyanate;

R₁ and R₂, which are identical or different, denote a C₈ -C₃₀, preferably C₁₀ -C₂₀, and more particularly C₁₂ -C₁₈ alkyl or alkenyl radical;

a_(i) and b_(i), which are identical or different, being such that the sum of a₁ +b_(i) ranges from 20 to 200 moles, and preferably from 60 to 120 moles;

the molar ratio a_(i) /b_(i) is between 30/70 and 90/10, preferably between 50/50 and 90/10 and more particularly between 70/30 and 85/15.

The compounds of the formula (I) which are more particularly preferred are those where A denotes the hexamethylene diisocyanate residue; R₁ and R₂ denote a lauryl radical or a mixture of radicals derived from tallow; the radicals R_(i) --[(C₂ H₄)--(C₃ H₆ O)].sub.(a.sbsb.i.sub., b.sbsb.i.sub.) preferably have a molecular weight of the order of 4000, with R_(i) denoting R₁ or R₂ and a_(i) and b_(i) denoting a and b or a' and b' as defined above.

The compounds of the formula (I) can be obtained by reaction of a diisocyanate with one or two polyoxyethylenated and polyoxypropylenated fatty alcohols of formula R_(i) [(OC₂ H₄)--(OC₃ H₆)] OH in which R_(i), a_(i) and b_(i) denote R₁ or R₂, a or a' and b or b' which have the meanings given above, which is(are) used in excess relative to the diisocyanate so that the latter is completely consumed.

Compounds of the formula (I) which may be used according to the invention are described in European Application EP 260 430 and marketed under the DAPRAL T210 and DAPRAL T212 by AKZO.

The compositions according to the invention may be provided in the form of liquids which are more or less thickened, gels, emulsions (milks or creams), dilute alcoholic lotions, dispersions, or aerosol foams.

The compositions are for example lotions, milks or emollient creams, lotions, milks or creams for the care of keratinous materials, make-up removing creams or milks, foundations, sun lotions, milks or creams, artificial tanning lotions, milks or creams, shaving creams or foams, aftershave lotions, eye make-up, blushers and foundation for the face, shampoos, bath or shower products, compositions to be rinsed off, to be applied after shampooing, dyeing, bleaching, permanent waving or hair straightening.

The compositions conforming to the invention may optionally contain, in addition, various additives which do not alter the properties of the compositions, such as anionic, cationic, amphoteric or zwitterionic surface-active agents, nonionic surface-active agents other than those described above, anionic, nonionic, cationic or amphoteric polymers, proteins, hydrocarbon-containing oils such as synthetic oils such as isoparaffins or inorganic, vegetable or animal oils, silicone oils, waxes, resins and/or gums, acidifying or alkalinizing agents, preserving agents, active ingredients, other thickeners, suspending agents, emollients, sunscreen agents, perfumes or other adjuvants commonly used in cosmetics.

The compositions conforming to the invention are applied to the skin or the hair in a cosmetically effective amount, depending on the nature of the composition.

A special application of the compositions according to the invention is the application as cosmetic composition for washing and treating keratinous materials, preferably the skin and the hair, and more particularly as shampoo. In this case, the shampoo is applied to wet or dry hair in effective amounts so as to wash them, this application being followed by a rinse.

The following examples are intended to illustrate the invention without, however, being of a restrictive nature.
